  Effect of adsorption temperature on heat and mass transfer characteristics of the adsorption air conditioning system The heat and mass transfer characteristics of the honeycomb desiccant dehumidifier (HDDH) for each adsorption temperature have the appearances shown in Fig. 3 (a) and (b) for Nusselt number (Nu) and Sherwood number (Sh Cited by: 8. The adsorption dehumidifiers using a technology based on the use of materials naturally drying (ie endowed with high physical-chemical affinity towards water vapor), as the silica gel. This operation technology makes them suitable for use in environments where they are required humidity values even at low temperatures and constant values dew. Adsorption-type Dehumidification This method is based on the moisture recovery from air by its absorption with absorbent materials. Adsorption-type dehumidifiers are used for dehumidification by this method; the principal item of DanVex dehumidifier is a rotating cylinder (rotor) with drive assembly, fan, heater and filter. The results confirm that this kind of adsorption chiller is an effective refrigerating machine though its performance is not as fine as the prediction results. Also it is well effectively driven.

In unheated environments or when water has penetrated deep into a structure, drying using an adsorption dehumidifier is the ideal solution. Corroventa’s adsorption dehumidifiers are available in both analogue and digital models, but all models share certain features; they are powerful and robust, compact and user-friendly, and they have a long service life. Introduction to Adsorption: Basics, Analysis, and Applications presents adsorption basics that are relevant and essential to its application, including data analysis, interpretation and design calculations. The book deliberately keeps background information to a minimum, instead comprehensively covering adsorption of liquid solutions, the. A compressor based dehumidifier uses a compressed refrigerant to cool metal coils (evaporator coils). The hot humid air that enters the dehumidifier condenses on these cool coils. This leaves the air that exhausts out of the dehumidifier still warm but drier than when it entered. Desiccant dehumidifiers work quite differently. Instead of using condensation (on Read More». Welcome to DehuTech AB Manufacturer and supplier of desiccant dehumidifiers and desiccant cooling equipment. DehuTech AB™ is a Swedish company that exports desiccant (adsorption) dehumidifiers to countries outside Sweden. The desiccant dehumidifiers are developed, designed and manufactured for the demanding Swedish desiccant dehumidifier market.

Types of adsorption Physisorption: physical adsorption Chemisorption: chemical adsorption heat of adsorption usually in the range of kJ mol-1 High heat of adsorption in the range of kJ mol of attraction are Van der Waal's forces Forces of attraction are chemical bond forces usually takes place at low temperature. These types of dehumidifiers are sold all over the place, so you will be able to find one very easily. If the dehumidifier that you are looking at does not say that it is a desiccant dehumidifier, then chances are that it is a typical refrigerator-style dehumidifier model. The high-density silica is the common type of silica gel used in adsorption systems such as Fuji Davison types ‘A’ and ‘RD’ silica gel, which have pore diameter in the range of – nm, the pore volume is – cm 3 /g and the specific surface area is – m 2 /g. The other types of silica gel with relatively high pore. z The importance of the adsorption control in various applications ⇒ described in text book. (p~) Adsorption at the solid-vapor interface Solid characteristics are history-dependent. So, detailed discussion of adsorption onto solid surfaces must include knowledge of “historical” elements.
